Flutterfire throws a dart not found error

Question

I'm following the flutter + firebase codelab, and I'm stuck at configuring firebase in my android app, I've already installed the flutterfire cli globally on my machine and exported the bin in my path.

export PATH="$PATH:~/source/flutter/bin"
export PATH="$PATH":"$HOME/.pub-cache/bin"

But still, the following error is thrown when I try to use the flutterfire cli.

flutterfire
/home/dio/.pub-cache/bin/flutterfire: 8: dart: not found

This error leads me to believe that dart is not installed on my system but....

Answer 1

I was facing this same problem, so I looked into the file that stores the code for flutter fire command in bash.

This file is stored in the ~/.pub-cache/bin/ I looked up the code inside this file. What the code basically does is, it passes over whatever command that you have given, to this other command

dart pub global run flutterfire_cli:flutterfire{your command}

So, if you want to run a command say, flutterfire configure, you can run it this way,

dart pub global run flutterfire_cli:flutterfire configure

I hope this answer helps!!.

I was able to work around this issue by calling the bin directly, like so:

dart /home/foo/.pub-cache/global_packages/flutterfire_cli/bin/flutterfire.dart-2.17.0-239.0.dev.snapshot configure

This is weird since I'm calling the cli through the same path specified in at ~/.pub-cache/bin/flutterfire

  dart "/home/foo/.pub-cache/global_packages/flutterfire_cli/bin/flutterfire.dart-2.17.0-239.0.dev.snapshot" "$@"

You can remove the first line from the /home/YOUR_USERNAME/.pub-cache/bin/flutterfire file and the flutterfire command should work properly.

Remove this line:

#!/usr/bin/env sh

Keep the rest

Also, check this post modify path, did not work for me though.

1. First make sure you are in the directory of the project you want to use in flutter
2. Next install node.js using this link (we used the latest version) : https://nodejs.org/en/
3. Then install firebase tools using: npm install -g firebase-tools
4. Make sure that firebase is in your path by running firebase --version
5. Make sure flutter is in your path way. you can do this by going into finder and locating the flutter sdk. once located, right click click on getInfo, and then you will see "where", then right click and copy path. Go back to the same terminal window and use this command export PATH="$PATH:[PATH_TO_FLUTTER_SDK]/flutter/bin"
6. Check if it is really in your path by running flutter doctor
7. Next you want to delete this file called pubspec.lock by running this command rm pubspec.lock
8. Lastly run this command to install all the tools for flutter fire:
   dart pub global activate flutterfire_cli

You should be able to use it now. Some helpful links to use are https://firebase.flutter.dev/docs/cli/ https://firebase.google.com/docs/cli?authuser=0&hl=en#sign-in-test-cli

I was facing this issue on Ubuntu, the problem is that the script which essentially stands for the flutterfire command uses #!/usr/bin/env sh as shell, replacing it with #!/bin/bash solved the issue for me.

How to do that:

1. Navigate in the file explorer to ~/.pub-cache/bin/ and open the flutterfire file in a text editor, alternatively you can use nano ~/.pub-cache/bin/flutterfire
2. Replace the first line of that file from #!/usr/bin/env sh to #!/bin/bash
3. Save the file
4. Run flutterfire command and enjoy ;)
